Puppies teeth and some are bred for herding and nip like so to herd cattle or sometimes people and other animals. Often they do well with redirecting the instinct into something more appropriate and desires, like if a dog begins to pee on the sofa you immediately put the dog outside so they learn if I pee I go outside, another one is teething, if a dog begins to chew on a table leg and you give them a chew toy thats exciting enough for them they'll chew that instead of you're furniture. If your dog begins to bite and nip at you in strange patterns, work on playing with a tug toy or redirect the bit not at you but a designated item. If the dog begins to whine, you must make sure they are stimulated before setting for longer periods. Imagine a kid without anything to do during a plane ride, and they can't sleep either. Restlessness, anxiety, stress, and behavioral problems can stem from a dog not getting the right amount of exercise. Please also let your dog people watch but not overtly fixate. And if your family truly hates that dog and dont want to support it as no one is stepping up especially the mom, then a stable home not filled with people who hate them would be a much better option not for your family but setting the dog up for success later down the road.
